Channel Master Ultra Mini 8 - 8-Port TV Antenna Distribution Amplifier, 4.5dB gain, Compatible with Non-Amplified TV Antennas, Cable TV and Internet Modems, Increases Signal Strength, Indoor/Outdoor

It deserves 6 stars. Great rugged piece of equipment. Channel Master makes some good gear. I could tell the quality by the short cable they included for powering the unit, which is the highest quality.Easy to install, works great. Has power indicators on both the power supply and the distributor unit.Recommend.!

I'm a Boomer, so I'm old enough to remember that the promise of cable TV was, "no commercials". Since they haven't lived up to that promise they don't get any of my money.I have a rooftop antenna and its coax cable runs into my utility room where it then splits to 4 locations in the house. I had only a passive 4-way splitter, my signal had really degraded and I was not looking forward to scaling the second story roof to check the antenna, which is only 5 years old. But, even my strongest broadcast signals were only in the 60 -70% quality range and I'd completely lost a number of UHF stations. So, after reading a lot of reviews, I took a shot and bought a "Channel Master 3414 4 Outputs Distribution Amplifier" from Amazon. Choosing it because the reviews and the price, because the power cable was included in that price, where with others it was a separate purchase.I've had it installed for two months now and I could not be happier with it. I live in a major metropolitan broadcast market so with the Channel Master I am now pulling in 40 different stations. All of the VHF stations are now showing 100% signal strength and signal quality and most of the UHF stations are showing the same. Even the very weakest UHF stations, which I couldn't even watch before as they had less that 3% signal quality, are now showing over 50% signal strength and over 30% signal quality, which for a digital transmission still gives you good picture and sound.So, if you want to have great reception from a rooftop antenna that is split and routed to numerous televisions, while telling the cable and satellite folks to take a hike, I highly recommend the "Channel Master 3414 4 Outputs Distribution Amplifier"Don't forget, if you are not going to use all the ports you will need to cap any unused ports with an F Type 75 Ohm Terminator cap or you could have signal loss even with the amplifier.UPDATE June 30, 2014: It's now well over a year since I installed the Channel Master amplifier and it's still doing a bang up job. Recently I had some work done on the house and decided while there were pros up on the ladders to have them replace my 6 year old "airplane" shaped antenna with a new Terrestrial Digital DB8 Multi-Directional 'Bowtie' UHF DTV Antenna. The new antenna is mounted about 5 feet above the roof peak, which is about 20 foot high. Living 8 miles from downtown Chicago the Channel Master/Terrestrial Digital DB8 combination is now pulling in 70 channels and when you discount the duplicates broadcasting on two frequencies, one HD one not and the weaker ones, I have well over 50 strong, viewable, channels. The interesting thing is I get different channels depending on the brand of the TV or converter box. For example with my Toshiba LED TV's tuner I get a series of Channel 13s but not the series of Channel 22s I get with the Zenith converter box in the same room which does not get the 13s. I've actually gotten a little hooked on the subtitled Korean historical costume dramas running on one of the Channel 24s I get. My only regret is I wish I'd put another 5 foot extension on the antenna mast; I think if I had I would probably be able to pull in the Northern Indiana stations around Merrillville, Hammond and Gary.So, I'm still 100% behind my 5 start ratting for the Channel Master.

Needed this to set up an antenna. Signal was adequate and provided enough power to pull the news during hurricanes when running off a generator. Just screw in and plug in - easy to use and did a great job.

The Channel Master CM-3410 signal distribution amplifier worked very effectively with my television sets. My home is only about 12 miles from most local TV transmitters, but reception had been problematic because we employ indoor antennas some distance away from our TV sets. Most challenging was a basement TV fed from an antenna by a window at the other end of the room. Only a few channels came in reliably on this TV. Reception on our upstairs TV, also relying on an antenna in a window, was better. For both sets, frequent antenna adjustments were necessary to obtain satisfactory reception. And human movement in a room could cause some images to become pixilated or disappear.The labeling of the terminals on this amplifier can be confusing, because it is tiny and nearly illegible, and its terms may seem ambiguous. (1) On one side of the amplifier is a single terminal, labeled "PWR IN / RF OUT +15db." A coaxial cable goes from this terminal to the TV. (2) Directly opposite this is another terminal, labeled "PWR IN / 12-16VDC 250 mA." A coaxial cable connects this terminal with the DC power converter, which plugs into a regular AC outlet. (3) Next to the power terminal is a third terminal, labeled "RF IN / REV OUT -1dB." For off-air reception, the coaxial cable from the antenna attaches to this terminal. The amplifier comes with a 6-foot coaxial cable to connect the DC power converter to the amplifier. You will need separate coaxial cables to connect the amplifier to the antenna and to the TV. The lengths of the cables needed will vary according to the locations of the antenna, the DC power converter, and the TV. In general, it is best to keep the amplifier as near as possible to the antenna. Just keep in mind that you will need three separate F-Pin to F-Pin coaxial cables, only one of which is included with the amplifier.Both of my TVs are served with RCA digital flat multi-directional antennas, whose built-in 6-foot cables attach to the amplifiers. The basement amplifier is connected to the TV with a 20-foot cable; but only a 6-foot cable was required to connect the other amplifier with the upstairs TV. These antennas did not work very well with 10db gain amplifiers. But with the 15db gain CM-3410 amplifier, the basement TV pulled in all the desired stations--mostly without any adjustment of the antenna. The results were so good that I acquired a second amplifier for the upstairs TV, and it solved nearly all the problems we had been having with it.The effectiveness of this amplifier will depend on your specific situation. (See other reviews.) It may not help to pull in a distant signal via an indoor antenna. But if you are getting poor reception of certain stations, this amplifier may be the solution.
